After upgrading to Xorg 1.7.5-1-i686 (Arch Linux) my system freezes in a
different way. I can move only mouse cursor, but... I can switch to a
terminal and kill Xorg :-) . And I don't get freeze after lid close
anymore. After a freeze in logs I see many (I mean really a lot!) lines
like:

Feb 21 14:51:00 d500-kleofas kernel: [drm:i915_gem_execbuffer] *ERROR*
Execbuf while wedged

and

Feb 21 14:49:41 d500-kleofas kernel: [drm:i915_gem_execbuffer] *ERROR* Execbuf while wedged
Feb 21 14:49:41 d500-kleofas kernel: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Feb 21 14:49:41 d500-kleofas kernel: render error detected, EIR: 0x00000000

and also after a freeze when I try to restart KDM in logs I get a lot of:
(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Input/output error.

kernel: Linux 2.6.32-ARCH
Xorg 1.7.5-1-i686
intel driver 2.10.0-1-i686
libdrm: compiled from sources from Geir Ove Myhr's post.
